## Long description

PULSAR HPSB-12V7A-D is a buffered switch-mode power supply that delivers a stabilized 13.8 V DC output with a maximum current of 7 A and includes a built-in 40 Ah battery capacity for backup. The unit is designed for continuous mains-fed operation and automatic standby power from the internal battery when mains supply fails. It provides regulated power and battery charging management suitable for security equipment, access control, CCTV cameras, and telecommunications devices requiring reliable 13.8 V DC supply.
Advantages
The switch-mode design ensures efficient power conversion and reduced heat generation compared with linear supplies. Integrated battery buffering and automatic switchover provide uninterrupted operation during mains interruptions. The supply offers regulated output voltage to support sensitive electronic equipment while managing the charging process for the connected sealed lead-acid battery to prolong service life. Compact construction and mounting provisions simplify installation in control cabinets or equipment racks.

How to use
Install the unit in a dry, ventilated cabinet or rack following local electrical regulations. Connect the mains input to an appropriate AC supply and verify proper grounding. Attach the battery leads to the designated battery terminals observing correct polarity and secure connections. Connect the 13.8 V DC output to the load, ensuring the total current draw does not exceed 7 A. During normal operation the unit will supply the load and maintain the battery charge; on mains failure it will automatically switch to battery power. Periodically inspect battery condition and terminal connections and follow the battery manufacturer's guidelines for replacement intervals.
Usage recommendations
For reliable long-term operation, use a sealed lead-acid battery type recommended for standby applications and ensure ambient temperature remains within the manufacturer's specified range. Avoid exceeding the rated output current and provide adequate ventilation around the unit. Schedule periodic battery tests and replace the battery when capacity drops below recommended thresholds to maintain backup performance.
